One more prompt from the OSR Discord "Secret Jackalope 2022" writing prompts (Round 2 assignments). This time, "Nonstandard creatures with useful bits and how to harvest them" via user @wyattwashere.
Nonstandard creatures, eh?
Well, OK. I guess I'll delve back to the lunacy that is the 1981 Fiend Folio and pull up a few uncommon (and at least one better-known) critters and make up some stuff.
The harvested organs and products are each one element in the creation of their respective products, and other undetermined ingredients or reagents will be required....
1d7 Unpleasant Monsters and Their Useful Bits
The Adherer - The adherer is a creature resembling a mummy, but is not an undead. Instead, it secretes a “resinous solvent” that causes any weapons to stick to it until the creature is slain. Fortunately, it is susceptible to fire, and boiling water, in sufficient quantities, can break the adhesive's grip. The adhesion breaks down 5-10 turns after the creature's death.
Product: Although the excretions from this creature have been rumored to be ingredients for sovereign glue or universal solvent, wise practitioners of the alchemical arts know that this is folly. However, the “glue” has been incorporated into another reagent to help deal with more ghostly foes:
Spirit Gum: An application of this viscous fluid will cause an incorporeal foe to become semi-corporeal for 2d4 rounds, allowing them to take half-damage from non-magical weapons during that period.
Adhesive from two adherers is required to create one use of spirit gum. The adhesive must be collected immediately upon the adherer's death by dissolving the adhesive in four gallons of hot water. The water is then distilled off to provide raw material for creation of the gum.
Crypt Thing – This is a moderately powerful undead whose primary defense/effect is to teleport its foes to a random location (100-1000 feet distant, or up/down one dungeon level).
Product: Arcane research has determined that this ability lies within the shriveled pituitary of the creature, nestled at the base of its mummified brain. Upon slaying one of these challenging undead, a knowledgeable individual may be able to identify and remove the gland with a magical weapon.
These may be used to create a Wand of Teleportation at half the time and expense. However, because of the corruptions inherent within the crypt thing's preservation and reanimation, there is a 2 in 20 chance that use of the item will send the user in a random direction consistent with the crypt thing's inherent abilities (table from FF, below).
Disenchanter – This aggravating creature's ability is magic drain, as it "feeds" on magical energy, attacking enchanted items and sucking out the magic through its extensible snout.
Product: The capacitor-like organ where a disenchanter "digests" enchantments resembles a stomach, but is packed with filaments capable of absorbing arcane energies. From this organ, an expert biomancer may create one of two devices.
